7.68 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing presents one beautiful translucent brown moonstone weighing 7.68 carat, set in an elegant oval shape, with precise dimensions of 13.76 x 9.66 x 7.88 mm, and finished as a classic cabochon. As a member of the feldspar group, moonstone is most prized for subtle optical phenomena, most notably adularescence, which appears as a soft, floating sheen above the body color when light interacts with fine lamellar structures within the crystal. The specimen offered by The Natural Gemstone Company shows a delicate, light brown tone with light color intensity, which allows the adularescent effect to remain visible without overpowering the stone. The excellent polish enhances surface smoothness and the cabochon profile maximizes the play of light while protecting the stone from everyday wear. The combination of nearly eight carats and a substantial depth of 7.88 mm provides a pleasing heft and presence for pendant or statement ring designs, while the oval outline lends classical symmetry that is straightforward to set and style.

Clarity and inclusion characteristics are central to valuation for educated buyers, and this moonstone carries a clarity grade of very slightly included, evaluated at eye level. This grade means that inclusions are minor and do not detract from the stone when viewed without magnification, yet they are natural features that confirm the gem is untreated and earth formed. In moonstones, subtle internal textures often contribute to the optical effect rather than degrade it, so inclusions can be an asset when they enhance adularescence or create attractive internal glow. The observed translucency is desirable for a brown moonstone because it allows light penetration and internal scattering, both of which are necessary for a vibrant sheen. For collectors and connoisseurs, a very slightly included rating paired with eye level inspection rather than loupe based grading provides practical clarity information for wearable gems, since it reflects the real world appearance under normal viewing conditions.

Cut, proportions, and polish are equally important to the educated buyer, and the cabochon execution of this stone is a deliberate trade off between optical performance and durability. Cabochon cutting is the standard for moonstone because it preserves the oriented lamellar layering that produces adularescence, and it prevents the loss of sheen that would occur if the stone were faceted. The oval shape offers efficient material yield and balanced light distribution across the surface, making it suitable for a wide range of settings, including bezel mounts, low profile prongs, and custom designs that emphasize the stone as a focal element. Practical considerations for jewelers include the 13.76 mm length and 9.66 mm width, which correspond well to most ring heads and pendant bails, and the 7.88 mm depth which ensures solidity while allowing comfortable integration into protective settings. From a market standpoint, a cabochon of this size and clarity from a recognized source is attractive to designers and collectors who value natural optical phenomena and reliable physical proportions.

Provenance and treatment disclosure are key trust factors for knowledgeable buyers, and this moonstone is reported as originating from Ceylon Sri Lanka, a historic and well regarded locality for quality moonstones with fine adularescence and clean material. Enhancement no enhancement is declared, indicating the stone is in its natural state without dyeing, heating, or other modifications that could alter its appearance or long term stability. Natural origin and lack of treatment typically enhance desirability for collectors who prioritize geological authenticity and long term value. At The Natural Gemstone Company we emphasize transparency and ethical sourcing, and we are prepared to provide additional information or imagery on request to support appraisal, design, or certification processes. For care, avoid ultrasonic cleaners and steam, clean with mild soap and warm water and a soft cloth, and set in protective mountings to guard against hard knocks because feldspar minerals have moderate hardness and can chip under impact. This moonstone presents a harmonious combination of provenance, natural optical character, and wearable proportions, making it an informed choice for the buyer seeking an elegant, ethically sourced, and visually engaging gem.
